Review count and SteamSpy's owner range agree well enough to narrow the estimate down to this band. Multiplied by the $1.99 launch price — there is not enough price history for this game to weight the copies by what they actually sold for. Before Steam's cut, VAT and refunds. How these numbers are calculated.
